| p.1 #1 · p.1 #1 · Sony RMT-P1BT Remote Third-Party Focus Adjust Compatibility List | |
The Sony RMT-P1B allows you to rack the focus point forward or back without touching the lens or camera. This feature immensely useful for focus stacking in the field, as it allows you to take focus stacks with less muss and fuss than having to physically and manually adjust the focus.
To set up the system to work this way, you have to set the lens AF/MF switch to "AF" and the camera focus mode to "MF". Then to capture a focus stack:
- Manually set focus to the closest distance you want to be in focus by physically turning the focus ring.
- Take an exposure (or several, if exposure as well as focus bracketing).
- Then press the "+" key 1-3 times to advance focus a bit to the next focal plane
- Take another exposure (or several).
- Repeat above two steps until you get the focus slices you want (e.g., up to infinity, inclusive).
Very useful in macro as well as landscape photography!
As can be imagined, in works seamlessly and perfectly with OEM Sony FE lenses. Third-party lenses on the other hand, are a little less even. The purpose of this thread is to collect user findings regarding lens compatibility with this feature.
Lenses That Can Have Their Focus Adjusted
- Sigma 14-24 f/2.8 DG DN: Works!!
Update 2020-11-01: It Just Works. No muss, no muss, just like a native Sony lens.
This is different from what I previously found, where it worked, but in a weird way:
I struggled with this for a while, even speaking to a Sigma engineer who could not get it to work on his end. But then I finally figured out that pressing "AF-ON" after every press of "+" or "-" did get things to work. And then I discovered that focus was actually advancing, but did not register till the shutter was triggered or AF-ON was pressed. Note that the camera needs to be set up in MF focusing mode even though the lens AF/MF switch is the AF position, so AF-On does not actually do anything. Weirdness on top of weirdness ... but it works!

Batis: works, as tested by a Batis 135mm.
Lenses That CANNOT Have Their Focus Adjusted
- Canon EF 24-70 f/2.8 using the Sigma MC-11 adapter: focus cannot be adjusted remotely.
